(Phys.org) -- How do you determine who is doing the touching with a multi-user touch display? Microsoft Research has published a paper that presents a technique for doing so. The researchers make their attempt by fusing Kinect, ...

University of Nevada, Reno computer science engineering team Kostas Bekris and Eelke Folmer presented their indoor navigation system for people with visual impairments at two national conferences in the past two weeks. The ...

To achieve buff biceps, proper form for strength-training exercises is key, and people often turn to professional trainers to correct them and prevent injury. Cornell student engineers have developed an alternative: A simple ...

In the last decade, MEMS (microelectromechanical devices) have wrought revolutions in several industries: Arrays of micromirrors, for instance, enabled digital film projectors, and accelerometers like those in Microsofts ...

ColdQuanta Inc. of Boulder and the University of Colorado have finalized an agreement allowing ColdQuanta to commercialize cutting-edge physics research developed by CU-Boulder and SRI International. The licensed technology ...

The next generation of smart phone could combine the data from its gyroscopes with a built-in compass to allow you to track your movements when indoors even without GPS. Such a system could be useful for shopping mall managers, ...

Researchers have created new "microtweezers" capable of manipulating objects to build tiny structures, print coatings to make advanced sensors, and grab and position live stem cell spheres for research.

Firefighter Ray Hodgson hits the talk button on his walkie-talkie: "I have fire showing, possibility of a rescue on the third floor. Engine 35, initiate a rescue group. Also back him up with a hose line."

Accelerometer

An accelerometer measures the acceleration it experiences relative to freefall. Single- and multi-axis models are available to detect magnitude and direction of the acceleration as a vector quantity, and can be used to sense orientation, vibration and shock. Micromachined accelerometers are increasingly present in portable electronic devices and video game controllers.
